초록

A system for measuring and controlling the mass flow of a gas of variable characteristics within a pipe by a metering valve, wherein a Coriolis mass flow meter mounted in the pipe is connected to the valve processor unit to calculate a correction factor for the flow rate calculated by the valve and represented by the ratio of the values originating from the Coriolis meter to those originating from the valve, this factor being updated periodically when the operating conditions do not introduce an error into the Coriolis meter. A multi-valve system for dif...
